A surgical device includes a first jaw and a second jaw disposed in opposed correspondence with the first jaw. The second jaw is mechanically coupled to the first jaw at a proximal end opposite a distal end. A cutting element is disposed within the second jaw, and a first driver is configured to move the cutting element proximally from the distal end toward the proximal end of the second jaw to cut a section of tissue disposed between the first and second jaws. The device may also include a stapling element disposed within the second jaw. The cutting element and the stapling element may be contiguous so as to define a cutting and stapling element, such as a wedge having a blade disposed thereon. As the wedge is moved proximally from the distal end of the second jaw to the proximal end, the wedge pushes a plurality of staples against a plurality of opposing staple guides disposed in the first jaw in order to staple a section of tissue while cutting the section of tissue.

An electrosurgical generator has an output power control system that causes the impedance of tissue to rise and fall in a cyclic pattern until the tissue is desiccated. The advantage of the power control system is that thermal spread and charring are reduced. In addition, the power control system offers improved performance for electrosurgical vessel sealing and tissue welding. The output power is applied cyclically by a control system with tissue impedance feedback. The impedance of the tissue follows the cyclic pattern of the output power several times, depending on the state of the tissue, until the tissue becomes fully desiccated. High power is applied to cause the tissue to reach a high impedance, and then the power is reduced to allow the impedance to fall. Thermal energy is allowed to dissipate during the low power cycle. The control system is adaptive to tissue in the sense that output power is modulated in response to the impedance of the tissue.

A pump system for applying negative pressure to a wound, including a flow monitor capable of detecting a deviation from a reference airflow rate provided by a controlled leak to determine whether the system is operating normally or abnormally, and a flow status annunciator to indicate a normal operating condition or whether an abnormal condition is a leak or an occluded line in the system. The pump system further includes a pressure controller for regulating operation of a pump to control pressure in the system at a range around a user-selected setpoint. The pump system may also include a waste collector and a level sensor for detecting when the collector is full.

Electrochemical cells, and more specifically, rechargeable batteries comprising lithium anodes for use in water and/or air environments, as well as non-aqueous and non-air environments, are presented. In one embodiment, an electrochemical cell includes an anode comprising lithium and a multi-layered structure positioned between the anode and an electrolyte of the cell. A multi-layered structure can include at least a first single-ion conductive material layer (e.g., a lithiated metal layer), and at least a first polymeric layer positioned between the anode and the single-ion conductive material. The invention also can provide an electrode stabilization layer positioned within the electrode, i.e., between one portion and another portion of an electrode, to control depletion and re-plating of electrode material upon charge and discharge of a battery. Advantageously, electrochemical cells comprising combinations of structures described herein are not only compatible with environments that are typically unsuitable for lithium, but the cells may be also capable of displaying long cycle life, high lithium cycling efficiency, and high energy density.

The present invention relates to vacuum processing systems in which process gases are introduced in a process chamber and are exhausted through a vacuum processing system exhaust path. Deposits made by the exhausted gas are reduced or eliminated by introducing a reactive gas upstream of the device affected by deposits. The amount of introduced reactive gas is controlled by measuring gas phase concentrations of exhausted gas components upstream and downstream of the affected device, and, from those measurements, determining whether the components are being consumed in deposits on the affected device.

A system and method of use for permanently archiving intellectual properties (IP) in a digital archival system. An owner contributes each IP with an initial financial contribution including a discrete archival endowment which is sufficient to fund archival of the IP for an assured archival period. A plurality of discrete archival endowments can be pooled into one or more archival endowment funds, jointly managed for the maintenance of each archived IP. The endowment funds can be managed by a trustee separate from the management of the digital archive. Retrieval can be funded through retrieval fees or an endowment maintained separate from the archival endowment fund. Digital rights management can remunerate owners and revenue tracking can capitalize the value of each IP. Access to the archive system is preferably through a variety of membership options including owners, users, and partners.

Composition and methods that include potassium nitrate for whitening and/or reducing tooth sensitivity. The dental compositions may optionally include a dental bleaching agent, such as hydrogen peroxide or carbamide peroxide. The dental compositions may be applied directly to the person's teeth, or they may be loaded into a comfortable fitting, flexible, thin-walled dental tray and placed over the person's teeth. In that case, the dental compositions will include a tackifying agent, such as carboxypolymethylene, which assists the composition in retaining the dental tray over the person's teeth as a result of the adhesive properties of the dental composition rather than due to mechanical interlocking of the tray over the person's teeth. The dental compositions may further include anticariogenic and antimicrobial agents.

The present invention is a method for operating a backlighted dot matrix type LCD for displayed outputs from a programmable environmental control device, such as a programmable thermostat. The LCD is operated so that viewer elements of a displayed data item are non-opaque when a room where the LCD is located is darkened and the surrounding display elements are partially or completely opaque. Selected elements can also change from opaque to non-opaque to display an active condition.

A filter assembly is provided having a housing and a cover that communicate to retain a filter element. The housing has a top and a bottom spaced apart from each other, and a first pair of guide members is maintained beneath the top while a second pair of guide members is maintained above the bottom. The filter element is retained in the housing between the first and second pair of guide members thereby defining a first cavity between the top and the filter element and a second cavity between the bottom and the filter element. Fasteners, such as screws, rivets, nails and the like, may communicate with the cavities without damaging the filter element. The first and second pair of guide members allow for access to the internal surface area of the top and bottom of the housing such that fasteners or other installment means can be employed from the inside of the housing outwardly to the duct work or framework to which the filter assembly is to be attached.

A semiconductor package contains a metal leadframe that has been specially treated by roughening it with a chemical etchant. The roughening process enhances the adhesion between the leadframe and the molten plastic during the encapsulation of the leadframe and thereby reduces the tendency of the package to separate when exposed to moisture and numerous temperature cycles. In one embodiment, the leadframe made of copper is roughened with a chemical etchant that contains sulfuric acid and hydrogen peroxide.
